Used by the routine at ReadActionFlags.
Returns zero unless SearchObjectTable passes and the top two bits of the action flags are 128. A match is stored at 47643+3 and passed to CheckBitAndProcess.

| CheckObjectAttribute | 48161 | CALL SearchObjectTable | Go to CheckObjectAttribute_Next if the object table ends before the moved marker. | |
| 48164 | JR NZ,CheckObjectAttribute_Next | |||
| 48166 | LD A,(IX+3) | Jump to CheckObjectAttribute_StoreRecord if the top two bits of the action flags are 128. | ||
| 48169 | AND 192 | |||
| 48171 | CP 128 | |||
| 48173 | JR Z,CheckObjectAttribute_StoreRecord | |||
| CheckObjectAttribute_Next | 48175 | XOR A | Clear A. | |
| 48176 | RET | Return. | ||
|
Stores this record and tests it.
|

| CheckObjectAttribute_StoreRecord | 48177 | LD (47646),IX | Store this record at 47635+11 and call CheckBitAndProcess. | |
| 48181 | CALL CheckBitAndProcess | |||
| 48184 | JR Z,CheckObjectAttribute_TestActionSucceeded | Go to CheckObjectAttribute_TestActionSucceeded if the attribute needs no extra bit handling. | ||
| 48186 | LD A,1 | Write 1 to the flag at 47635+10. | ||
| 48188 | LD (47645),A | |||
| 48191 | SET 0,(IX+3) | Set the action-pending flag. | ||
| CheckObjectAttribute_TestActionSucceeded | 48195 | OR %00000001 | Reset the zero flag. | |
| 48197 | RET | Return. | ||
